interlaced mpeg2 encoding P & B frames rate distored interlaced mb decission alternate scantable support 4mv encoding fixes (thats also why the regression tests change) passing height to most dsp functions interlaced mpeg4 encoding (no direct mode MBs yet) various related cleanups disabled old motion estimaton algorithms (log, full, ...) they will either be fixed or removed Originally committed as revision 2638 to svn://svn.ffmpeg.org/ffmpeg/trunk
